Any suitable medium for producing the desired My invention relates to a butter print machine low temperature may be employed; as for examto which the bulk butter is automatically fed into ple a dry insulating medium such as cork, indi- 55 cated at 20, may be used; the entire chamber or space intermediate of the main walls I0 and the outer shell I9 being properly fllled with the insulation.

The throat or delivery end I6 of the machine is of less vertical dimensions, produced by an intermediate or transverse wall 2| which terminates at bottom in the longitudinally disposed wall 22 arranged in close proximity to the screws or worms I2, as shown in Figure 2.

This throat portion of the machine at the upper side is provided with the outer shell section or metallic wall 23, which is preferably integrally united with the main wall by soldering or otherwise; and the chamber filled with suitable insulating material as indicated at 20.

It has been found in practice, and particularly under certain working conditions, that the butter has a tendency to adhere at the throat and thus clog the passage therethrough, thereby destroying the desired uniformity and posltiveness. In order to force the butter into positive feeding contact with the worms, operators were compelled to use suitable paddles or implements, frequently having fingers caught by the worms. In order to provide a more positive feed and at the same time a safe and more sanitary method, I provide the movable compressor member 24 which is pivotally mounted at its lower end so as to swing through the arc of a vertically disposed circle.

The compressor or feed member 24 is preferably of metal, curving upwardly from its lower end, with its butter engaging side transversely undulated or formed with a double concavity conforming more or less with the tops of the worms I2.

That is to say, member 24 on each side of its longitudinal median line is dished or concaved as shown at 25, 25, see Figure 5, in order that the feed control member 24 may be brought into close relation with the tops of the feed worms I2, I2, When occasion requires.

The member 24 is pivotally mounted at its lower end by means of the hollow trunnions or nipples 26, 26, which are journaled in the sleeves or bushings 21, 21, secured in the side walls of the main casing III and also preferably extending through the outer shell or walls I9 as shown; the sleeves or bushings being also preferably intimately secured tothe casing walls and outer walls so as to prevent ingress of air into or egress from the insulation chamber.

The feed member 24 preferably consists of a hollow or chambered casting whereby a water receiving chamber 28 is provided, with which the hollow trunnions or nipples 2E, 26 communicate. With this arrangement, water of the required temperature, is introduced through one nipple 26 and discharged from the feed member through the other nipple 26, thus permitting a constant circulation of the tempering water or other medium to be maintained.

The feed member is made with the upward curvature so as to gradually subject the butter to compression in the event it is found necessary to prevent clogging at the entrance to the throat portion I6 of the machine.

The upper free end of the feed member 24 is provided with a suitable handle as at 29, whereby the operator is enabled to properly depress the free end of member 24 against the action of spring 3|] whereby member 24 is returned to and held in its normally elevated position illustrated in Figure 2. The spring SIL-which is preferably of the coil type,-has one end secured to an eye-bolt 3l, fastened in the intermediate transverse wall 2l, while the other end of the spring is secured to the feed member by suitable means, such as the eye member 32. The spring is preferably secured adjacent the upper end of the feed member where its action is more effective in returning the water lled member 24 to its normal position shown in Figure 2.

By concaving the butter engaging side of the feed member, as shown and described, enables the sides of member to move in close relation to the side walls I5, I5 of the main casing IU, as more clearly shown in Figure 4, thus preventing the butter crawling or crowding upwardly along the sides of the machine.

The feed member 24 is shown pivotally mounted adjacent the vertically disposed intermediate wall 2I, with the result that the lower and comparatively wide end of member 24 will abut the wall 2| and thereby provide a stop for the action of the spring and prevent the too far upward swing of the feed member.

In order that the tempering medium or water will be prevented from owing directly through the feed member 24 and so it may be properly effective, I provide the feed member chamber 28 with a number of spaced apart partitions or baffles 33, as shown in Figure 6. Two of the baffles extend from the pivoted or nipple end of the member 24 and terminate short of the other end wall of the member; while the third or intermediate baiiie extends from the last mentioned end wall toward and terminates short of the pivoted end of member 24. This forces the tempering medium or water to flow in a circuitous manner from one nipple to the other and causes the entire feed member 24 to be brought to the desired temperature.

The specific exemplification of my invention is adapted to overcome certain objections encountered with butter print machines as heretofore constructed; and while I believe the form shown to be the best embodiment of the invention, certain modifications may be made without, however, departing from the spirit of my invention.

What I claim is:

l. A butter print machine comprising a main shell or casting having sides, ends and bottom walls, the bottom wall being formed to provide a pair of longitudinally disposed arcuate channels extending from end wall to end wall, the side and end walls at top being flanged outwardly. while the bottom wall is provided with downwardly and outwardly extending supporting flanges; a pair of feed worms disposed in said arcuate channels; and outer metallic walls secured to the side and end wall flanges and to the bottom wall flanges so as to provide hermetically sealed chambers about the main shell.
